Analyzing the main classifications of industrial touch screens

Many people know about industrial touch screens and often use them. For example, the phones, tablets, and some smart wearable devices we use every day all use this type of industrial touch screen, which shows that this type of industrial touch screen has a very wide range of uses. But many people are not very clear about its classification, do you know its main categories?

According to the characteristics of the structure, principle, and performance of industrial all-in-one machine touch screens, different types of touch screens are also suitable for different occasions. The following is the classification and introduction of different types of touch screens and their applicable places.

1. Surface acoustic wave touch screen: made of pure glass material, with excellent light transmittance, long service life, and good scratch resistance, suitable for various public places of unknown users. But due to the accumulation of dust and oil stains over a long period of time, it is more suitable for cleaner environments. Regular cleaning services are also required.

2. Infrared induction touch screen: This type of touch screen has a low resolution but is not affected by current, voltage, and static electricity, making it suitable for use in some harsh environments; Suitable for various public places, offices without infrared and strong light interference, as well as industrial control sites with less precise requirements.

3. Capacitive sensing touch screen: Due to the variation of capacitance with temperature, humidity, or grounding conditions, its stability is poor and often leads to drift phenomenon. Afraid of electromagnetic interference and drift, not suitable for use in industrial control areas and environments with interference. Can be used for public information queries that require less precision; Regular calibration and positioning are required.

4. Four wire resistive touch screen: This type of touch screen is not afraid of dust, oil stains, and photoelectric interference, mainly scratches. Suitable for public places with fixed users, such as industrial control sites, offices, homes, etc.

5. Five wire resistive touch screen: It has excellent sensitivity and transparency, a long service life, and is not afraid of dust, oil pollution, and photoelectric interference. It is suitable for various public places, especially for industrial control sites that require precision.
